Jerome Glisse 64d7b8bed8 drm/radeon: add si tile mode array query v3
Allow userspace to query for the tile mode array so userspace can properly
compute surface pitch and alignment requirement depending on tiling.

v2: Make strict aliasing safer by casting to char when copying
v3: merge fix from Christian

Samuel Li a0a53aa8c7 drm/radeon: Use direct mapping for fast fb access on RS690
This patch allows the CPU to map the stolen vram segment
directly rather than going through the PCI BAR.  This
significantly improves performance for certain workloads with
a properly patched ddx.

Use radeon.fastfb=1 to enable it (disabled by default).
Currently only supported on RS690, but support for RS780/880
and newer APUs may be added eventually.

Alex Deucher 278a334cbc drm/radeon: enable the async DMA rings in the CS ioctl
This enables the functionality added in the previous
patches.  Userspace acceleration drivers can use the
CS ioctl to submit command buffers to the async DMA
rings.

Alex Deucher 2e1a7674f6 drm/radeon: add new INFO ioctl requests
Add requests to get the number of shader engines (SE) and
the number of SH per SE.  These are needed for geometry
and tesselation shaders in the 3D driver as well as setting
up PA_SC_RASTER_CONFIG on SI asics.

Marek Olšák 57f5708383 drm/radeon: add a CS flag END_OF_FRAME
No version bump is required because setting the flag on older DRM has
no effect.

This only reserves the bit and doesn't use it. I assume we will use it
for buffer eviction heuristics.
